METAL LEG FOR FURNITURE.

Specification of Letters Patent.

Patented Nov. 9, 1915.

Original application filed July 14, 1913, Serial No. 778.877. Divided and this application filed April 23, 1$ 14.

Serial No. 833,875. 1

To all whom it may concern: Be it known that I, Gunner: L. HARRISON. a citizen of the l nited States. residing at Cleveland. in the county of Cavahoga and State of Ohio, have invented a certain new and useful Improvement in Metal Legs for Furniture, of which the following is a full,

clear. and exact description, reference being had to the accompanying drawings.

This invention relates to metal legs for furniture. and particularly to a hearing plate or tread for use with such legs.

The class of furniture to which my inventi'on is especially applicable. is shown in my forme application for l'nited States latcnt. Ser. No. 778.877. tiled July l-l. 1913. of which this application is a division.

The objects of my present invention are the production of a metal leg which is ver} strong. yet light of weight. and which is formed at its lower end for the reception of a bearing plate or tread: and the provision of a bearing plate which may be very easily applied to the lower end of the leg: which plate is so formed as to insure a smooth bearing of the plate upon a tloor or other supporting surface: and to provide means for very securely fastening the plate to the leg. and for preventing angular movement between the plate and the leg.

In the accompanying drawing. wherein similar reference characters d-e nate corresponding parts throughout the several views. Figure 1 represents a elevation of the lower end of a metal leg for furniture. having a bearing plate applied thereto: Fig. '2 is a central vertical section of the parts shown in Fig. 1: Fig. 3 is a bottom plan view of the leg and bearing plate: Fig. i is a horizontal section on the line l-r of Fig. 2: and Fig. 5 is a perspective of the bearing plate.

The leg 1 is of tubular formation. and. in the embodiment shown in thedrawings. is substantiallv square in cross section. An inwardly extending flange 2 surrounds the lower end of the and. being of substantially the same width throughout. leaves a square opening in the lower end of the The bearing plate '3 of substantially the same. outline as the lower end of the except that it has two of its diagonally opposed corners turned up to form proje tions 4. the projections being somewhat narrower. however, than the length of the edges from 'which meet at an angle to which they rise. The bearing plate is some smaller than the bottom of the leg, and its central portion is depre sed and is of spherical contour. as shown at 5. This provides a smooth and comparativel small bearing surface for the plate. An aperture (5 occupies the center of the depressed portion 5, and the metal surrounding said aperture is pressed upward or countersunk. so tospeak. to provide a recess for the reception of the conical head T of the screw 8. the purposeof which screw will be presently explained.

The flat portion of the bearing plate between I its edges and the depressed central port on 5 is adapted to bear against the underneath surface of the flange 2, and the projections 1'- of the plate are arranged to occupy diagonally opposed corners of the square opening that is surrounded by the flange '2 and against adjacent portions of which the edges of the projections l bear. as show-n clearly in l l. The projections, thus confined within the corners of the opening in; the lower end of the leg. provide very efficient. locking means for preventing angular movementof the bearing plate with respect to the lee.

An inverted U-shaped anchor plate 9 occupies a position within the lower end of the leg 1 and has its ends 10 bearing upon the inner surface of the flange "3. at diametrically opposite points. This brings a threaded hole 11. that is'docated at the center of the horizontal portion of the anchor plate. directlyabove thegaforesaid aperture 6 of the bearing plate. and in a position to receive the end of the screw R. l v means of this screw. the bearing plate and anchor plate may be sccurel drawn together and,

clamped to the flange 2. ll'hile' it is desirable to have the anchor phue U'made of very still mater al. it is sul'iicientlv resilient to yield under the action of the screw. and be placed therebvunder a slight tension. in

order that it may eti'ectivelv secure the screw against turning. p

llaving thus described my invention. what I claimis:'

l. The combination. with furniture. said leg having rected llai'ige at its lower a tubular leg for an inwardly diend portions of each other. of a bearing plate which has a portion for engagement with the outer surface of said flange and a projection for confinement betweenangularly disposed portions thereof,

an anchor plate which has portions that bear' each other. of an anchor plate within said leg that bridges diametrically opposite portions of the aforesaid flange. said anchor plate havinga threaded opening. a bearing plate for the lower end of the leg having a recess for the head of a screw and an aperture central within said recess, a screw which passes through said aperture and which has a head that is confined within the recess and is threaded into the opening of the anchor plate. and means for preventing angular movement of the bearing plate with respect to the leg. said means comprising a pair of upwardly extending lugs which arecarried by said bearing plate and are adapted to occupy corners between adjacent angularly disposed portions of the aforesaid flange.

3. The combination, with a tubular leg for furniture, said leg having an inwardly directed flange at its lower end, the inner edge whereof defines an angular opening, of a bearing plate having a depressed central portion and a flat. surrounding portion which bears against the outer surface of the said flange." the central portion of the hearing plate having an aperture, an anchor plate whichhas end portions that bear upon diametrically 'opposite parts of the inner surface of .the aforesaid flange and. which has a central threaded aperture, and a screw which passes through the aperture of the bearing plate and is threaded through the hole of the anchor plate, the bearing plate having a lag for engagement with the edge of the aforesaid flange.

4. The combination, with a tubular leg for furniture, said leg having an inwardly directed flange at its lowerend, the opening defined by the inner edge of said flange .being substantially rectangular, of a bearing plate which has a flat portion for engage ment with the outer surface of the aforesaid flange and a projection which is adapted to be confined within one of the corners of the rectangular opening, the bearing plate having a depressed central portion and an aperture at substantially the center thereof, the material surrounding said opening being pressed upward to form a conical recess. an inverted U-shaped anchor plate having ends which bear upon the inner surface of the aforesaid flange atdiametrically opposite points, said anchor. plate having a threaded opening which is arranged in axial alinement with the aperture of the bearing plate, and a screw threaded through said opening and extending through the aperture in the bearing plate and having a conical head that is contained within the conical recess of the bearing plate. Y

5. The combination, Witha tubular leg for furniture, said leg having aninwardly; directed flange, at its lower end, the opening defined by the inner edge of said flange being substantially rectangular, of a bearing' plate for engagement with the outer surface of the aforesaid flange which has a projection that is adapted to bev confined within one of the corners of the rectangular openmg, an anchor member within the leg, and means connecting the anchor member and p the bearing plate.

6. The combination, with a tubular leg for furniture which is substantially rectangular in cross section, eachside of. the leg having a flange that is directed inwardly from its lower end, abearing plate which is of substantially the same outline as the bottomof said leg and having a depressed central 'portion which is substantially spherical in contour and a flat surrounding portion which contacts with the underneath surfaces of the aforesaid flanges, said bearing plate having a central aperture, the material surrounding said aperture being pressed inwardly to form a seat, an inverted U-shaped anchor plate which has ends that are adapted to bear against the inner surfaces of certain'of the aforesaid flanges, said plate having a threaded aperture which'is in axial alinement with the aperture of the bearing plate, a screw which is threaded through the aperture of the anchor plate and passes freely through the aperture of the bearing plate, said screw having a head which occupies the aforesaid seat of the bearing plate, the bearing plate having diagonally opposed projections which fit in corners between ad]acent flanges whereby said bearing plate is GEORGE L. HARRISON.
